编译Linux内核4.4实现可读NTFS

 

 

环境：rehl7.2 x64 3G内存 3核 40磁盘

  [[email protected]~]# uname –r                    #查看内核

3.10.0-327.el7.x86_64

[[email protected] ~]# mkdir /sdb1                                              #建立挂载点/sdb1

[[email protected] ~]# fdisk /dev/sdb                                     #把所有空间给sdb1

[[email protected] ~]# mkfs.xfs /dev/sdb1                                 #格式化sdb1

[[email protected] ~]# mount /dev/sdb1 /sdb1                        #挂载

 

1、  下载相应内核源码包4.4

[[email protected]]# ls

linux-4.4.tar.xz

[[email protected]]#

2、  确认系统具备编译软件的基本条件，即make、gcc、gcc-c++、ncurses-devel

[[email protected]]# cd

[[email protected]~]# rpm -qa | grep make

make-3.82-21.el7.x86_64

automake-1.13.4-3.el7.noarch

[[email protected]~]# rpm -qa | grep gcc

gcc-c++-4.8.5-4.el7.x86_64

libgcc-4.8.5-4.el7.x86_64

gcc-4.8.5-4.el7.x86_64

gcc-gfortran-4.8.5-4.el7.x86_64

[[email protected]~]# rpm -qa | grep gcc-c++

gcc-c++-4.8.5-4.el7.x86_64

[[email protected]~]# rpm -qa | grep ncurses-devle

[[email protected]~]#                                                                     #没有ncurses-devel，重新安装

[[email protected]~]# yum -y install ncurses-devel

3、  解压内核源码包

[[email protected]~]# cd /sdb1

[[email protected]]# ls

linux-4.4.tar.xz

[[email protected]]# xz -d linux-4.4.tar.xz

[[email protected]]# ls

linux-4.4.tar

[[email protected]]# tar -xf linux-4.4.tar

[[email protected]]# ls

linux-4.4  linux-4.4.tar

[[email protected]]# du -sh linux-4.4

702M         linux-4.4

4、  配置内核编译参数

[[email protected]]# pwd

/sdb1/linux-4.4

      [[email protected] linux-4.4]# make menuconfig

[[email protected] linux-4.4]# vim .config

系统自带的是不支持的

[[email protected] linux-4.4]# vim /boot/config-3.10.0-327.el7.x86_64

 

 

  [[email protected]]#

[[email protected] linux-4.4]# cp /boot/config-3.10.0-327.el7.x86_64  /sdb1/linux-4.4/.config

cp: overwrite ‘/sdb1/linux-4.4/.config’? y

[[email protected] linux-4.4]#

[[email protected] linux-4.4]# make menuconfig

[[email protected] linux-4.4]# vim ./.config

 

 

5、  编译内核

//生成内核

[[email protected] linux-4.4]# make bzImage                #生成内核

//报错

  HOSTCC scripts/sortextable

  HOSTCC scripts/asn1_compiler

  HOSTCC scripts/sign-file

scripts/sign-file.c:23:30:fatal error: openssl/opensslv.h: No such file or directory

 #include <openssl/opensslv.h>

                              ^

compilationterminated.

make[1]:*** [scripts/sign-file] Error 1

make: ***[scripts] Error 2

[[email protected] linux-4.4]#

//解决

[[email protected] linux-4.4]# yum -y install openssl-devel

//重新生成内核

[[email protected] linux-4.4]# make bzImage                                    #半小时

 

6、  生成新内核的驱动模块

[[email protected] linux-4.4]# make modules                                     #1小时

//清空缓存

[[email protected] linux-4.4]# sync

[[email protected] linux-4.4]# free –m

 

7、  安装编译好的内核与模块

1）  安装模块

[[email protected] linux-4.4]# make modules_install

 

2）[[email protected] ~]# cd /sdb1/linux-4.4/

[[email protected] linux-4.4]# make install

 

 

8、  查看或修改GRUB菜单（为了确认是不是把内核安装好了）

[[email protected] ~]#vim /boot/grub2/grub.cfg

9、  重启系统，测试新内核工作情况

重启选择

 

查看新内核

 

 

 切记，在公司编译内核一定要在虚拟机上实验之后再搬到真机上去编译哦
